Myntra.com — Roadster shoes refund

I have ordered 2 shoes via Gpay Payment mode on 8th December 2021 and cancelled 1 of them on the same day, i was asked to wait for refund for 7-10 days as it was digital payment mode so i waited and after that i called for the payment they asked again to wait till 28th December as it was already initiated so i waited till 28th Dec but than too i didn't received my payment and now there customer service number is also invalid. From where to get my refund back ???
